Paramore issued their apologies to "Team Coco" on Twitter as they announced the cancellation of their appearance on tonight's episode of Conan. The band explained that the cancellation comes as a result of frontwoman Hayley Williams' being ill.
Due to Hayley being sick, we are canceling our performance on @conanobrien tonight. Apologies to Team CoCo, we hope you'll have us back!— paramore (@paramore) April 30, 2013
Team Coco followed up, wishing Hayley well.
